Vectored interrupts
What is the difference between vectored and non vectored interrupt Some says Non-Vectored Interrupts are those in which vector address is not predefined. The interrupting device gives the address of sub-routine for these interrupts. INTR is the only non-vectored ... in the system. The address of this common ISR is known to the CPU .. Does Daisy chaining follows poling?

Both internal and software interrupts are same ? Example : system call
Both internal and software caused by executing the program instructions . So both are same ?

Self-Doubt Priority interrupts
Under the SOFTWARE METHOD – POLLING heading. What is the meaning of this line? “In this method, all interrupts are serviced by branching to the same service program”. https://www.geeksforgeeks.org/priority-interrupts-sw-polling-daisy-chaining/

DMA,interrupts
True/false 1. To access bus the DMA does not issue an interrupt it is done through DMA-request and DMA-acknowledge wires. Interrupt is issued by DMA to CPU only after complete data is transferred to the specific memory address by DMA. 2. DMA interrupts the CPU whenever it needs to initiate I/O and also when it has finished I/O transfers.
